Question:
Technicians of a steam turbine manufacturing company have measured the following data for a simple 500 kW turbine:● Inlet state at T = 673 K and P = 40 bar, and● Outlet state at T = 378 K and P = 1.0 bar.Draw the steam expansion process in the T–s diagram of water (you can use the chart in Appendix A.3 or make your own diagram with relevant isobars and state points using EXCEL or MATLAB) and determine the turbine efficiency.
Data From Appendix A.3
